I came across this manga while I was searching for some good futanari material, and I wasn't disappointed. This name is a tricky one, but is relevant to the mechanics that happen in the in the manga. As a hentai/ecchi manga, it does a good job of incorporating action elements by doing the classic earth vs. Aliens battle while still maintaining that sexually perverted edges that keeps that part of the humor coming. The end of it, however is a amazing top off that actually made it really worth it.
